FIREPROOF CONSTRUCTION AND HANGER THEREFOR.

SEEGIlFE-QATICN formingpart of Letters Patent No. 675,486, dated June4:, 1901. Application filed February 21, 1900. Serial No. 6,028. (Nomodel.)

To (LZZ whom it may concern:

Be it known that I, GEORGE H. KUNNEKE, a citizen of the United States,residing at New York, county of New York, and State of New York, haveinvented certain new and useful Improvementsin Fireproof Constructionsand Hangers Therefor, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

This invention relates to improvements in fireproof constructions, theimprovements of the present invention having reference particularly tooverhead or ceiling constructions and to hangers for supportingceiling-rods from the beams.

It is the object of the present invention, briefly stated, to provide ahanger which can be expeditiously applied and which when so applied willsupport the ceiling-rods and the ceiling firmly and strongly and againstany tendency to sag or to become otherwise displaced, and, further, toprovide a hanger which, while effective for this purpose, will also besimple in construction and method of application and cheap as tomaterial and cost of manufacture.

As a full understanding of the invention can best be had from a detaileddescription of an organization embodying the same, such a descriptionwill now be given in connection with the accompanying drawings, whichillustrate the present invention in its preferred form, and in which-Figure 1 is a vertical section of a fireproof ceiling or overheadconstruction of a wellknown type containing the present invention in itspreferred form, the view being taken transversely to the ceiling-beams.Fig. 2 is a vertical section at right angles to Fig. 1 and looking inthe direction of the arrow 2 in that figure, the lathing and plasticmaterial, however, being omitted. Fig. 3 is a similar View, but lookingin the direction indicated by the arrow in Fig. 1. Fig. A is ahorizontal section through one of the beams, taken on the line a ofFigs. 1 and 2 and also omitting the lathin g and plastic material. Fig.5 is a section on the line 5 of Fig. 3, illustrating the manner in whichthe hanger is applied to andsecured about the beam; and

Fig. 6 is a detail in perspective of one of the hangers, illustratingthe shape of the hanger prior to its application.

Referring to said drawings, A represents a pair of ordinary flanged ironbeams; B, the wire lathing; (J, the plastic ceiling; D, the hangers, andE the ceiling-rods, on which the lathing is supported by wire ties e.

The invention consists in the hangers D, each of which consists of a rodor strip of bendable metal of any suitable shape in crosssection, butpreferably of the oblong section shown, so that the hanger will presenta broad bearingsurface to the ceiling-rod E and the flanges of the beamA and at the same time be of such thinness consistent with the strengthrequired as to be readily bent at its ends about the beam, so as to besecured thereto and firmly support the ceiling. The hanger D has a bodyportion at extending across the beam A and below said beam and theceiling'rod E and two end portions 1) c, of such length, respectively,that when bent inwardly toward each other the end portion 6 will lapover one of the flanges of the beam A and the end portion cwill entirelyoverlap the opposite flange of the beam and extend upward along the webof the beam, as illustrated in Fig. 1.

Before its application to the beam A the hanger D is of the shape shownin Fig. 0, with its end portions Z) c bent upwardly from its bodyportion a and also laterally therefrom in opposite directions, so thatwhen applied to the ceiling-rod E said end portions will lie on oppositesides of the rod E and the body portion of the hanger extend across therod in an oblique direction, as indicated by dotted lines in Fig. 4.

, Upon the application of the hanger to the ceiling-rod E the endportion 1) of the hanger is bent, by means of a hammer or other suitabletool, inwardly and downward upon the flange of the beam A, and the endportion 0 is then bent inwardly against the web of the beam, so as tohold the rod 0, and is then bent inward to conform to the angle betweenthe web and flange by striking it with a hammer or sledge at the pointindicated by the arrow in Fig. 5 until said end portion bears againstthe flange of the beam and a portion of the web thereof, as indicated inFig. 1. As the end portion 0 of the hanger is thus bent into positionthe body portion Ct thereof will by such bending of the end portion bedrawn up toward the beam A, so as to press the ceilingrod E firmly andsnugly against the lower end of the beam A, and the hooked end I) willbe drawn up tight on the opposite flange, securing a very tight firmsupport of the ceilingrods Er With this construction of hanger thelathing, with its plastic material or other form of ceiling supported byrods E, will be held firmly against any tendency to sag or to becomeotherwise displaced.

It will be understood that this form of hanger may be used forsupporting rods for other purposes than suspending a ceiling.

What I claim is- 1.. The combination with the beams and ceilingrodsextending transversely to the beams of an overhead fireproofconstruction, of hangers for the ceiling-rods each comprising a bodyportion extending across and below the beam and across and below aceilingrod and having at one end an inwardly and downwardly bent portionoverlapping the flange and web of the beam, the opposite end of the bodyportion being on the opposite side of the ceiling-rod and suitablysecured to the opposite side of the beam, substantially as described.

2. The combination with the beams and ceiling-rods extendingtransversely to the beams of an overhead fireproof construction,

of hangers for the ceiling-rods each comprising a body portion extendingacross and below the beam and across and below a ceilingrod and havingat one end an inwardly and downwardly bent portion overlapping theflange and Web of the beam, and at its other end an inwardly anddownwardly bent portion overlapping the opposite flange of the beam onthe opposite side of the ceiling-rod, substantially as described.

3. The combination with flanged beams A, and rods E extendingtransversely to the beams, of hangers I, each comprising a body portiona, extending across and under a beam and rod, and downwardly andinwardly bent endsb c on opposite sides of the beam-flange and onopposite sides of the rod overlapping the flange of the beam with theend portion 0 also overlapping the Web of the beam, substantially asdescribed.

4. A hanger comprising body portion a formed to extend across the bottomof a flanged beam and across and under a rod eX- tending transversely tothe beam and bendable end portions 19 0, adapted to overlap the oppositesides of a flanged beam and end portion a being of such length as tooverlap, when bent, a flange and the web of the beam, substantially asdescribed.

5. A hanger comprising body portion a formed to extend across the bottomof a flanged beam and across and under a rod eX- witnesses.
